1. Possible Effects of Oriented Magnetic Fields on Human Blood Pressure
Abstract Background: There have been scattered reports indicating the possibility that applied magnetic fields can lower human blood viscosity, which has been considered as encouraging for decreasing blood pressure as a result of greater fluidity. Additional motivation comes from partial studies in animals showing some response of vascular variables to magn

2. The effect of 1-mg versus 3-mg granisetron on shivering and nausea in cesarean section: a randomized, controlled, triple-blind, clinical trial
Abstract Introduction: Intra- and postoperative nausea, vomiting and shivering are mentioned as the most common problem following spinal anesthesia. The aim of this study is to compare two different doses of granisetron to control the shivering, nausea, and vomiting caused by spinal anesthesia in women undergoing cesarean section (C/S). Method: This study

3. Prone ventilation in intubated COVID-19 patients: a systematic review and meta-analysis
Abstract Background The efficacy and safety profiles of prone ventilation among intubated Coronavirus Disease 2019 (COVID-19) patients remain unclear. The primary objective was to examine the effect of prone ventilation on the ratio of arterial partial pressure of oxygen to fraction of inspired oxygen (PaO2/FiO2) in intubated COVID-19 patients. Methods Dat

4. The influence of sex and level of physical activity on maximum tolerance to mechanical pain
Abstract Background A difference in maximum tolerance to mechanical pain (MTMP) between the sexes is widely studied but there is still no consensus on whether the level of physical activity (PA) influences pain. Objectives To compare the MTMP between men and women with different levels of PA. Methods Sixty five individuals were divided in female (n = 35)

5. Orthostatic changes in blood pressure and survival in elderly cardiopaths
SUMMARY OBJECTIVE: The objective of this study was to analyze the association between orthostatic changes in blood pressure and mortality in elderly cardiopath patients. METHODS: A cohort of 455 elderly cardiopath patients, monitored at a referral outpatient cardiology clinic in Pernambuco, Brazil, from October 2015 to July 2018. The exposure groups were f

6. Carotid Subclavian Bypass for the Treatment of Coronary Subclavian Steal Syndrome
Abstract Coronary subclavian steal syndrome is an uncommon cause of angina in patients with a previous coronary artery bypass graft procedure. The patient had chest pain with the exertion of the left upper limb, difference in blood pressure between the left and right arm, occlusion at the ostium of the left subclavian artery. He underwent carotid subclavian

7. Modeling and Computer Simulation of Viscoelastic Crypt Deformation
ABSTRACT Colorectal cancer morphogenesis begins at the cellular level from cell mutations in the intestinal epithelium cavities called crypts. These mutations lead to a pressure difference in the epithelium crypt walls, which can cause deformation and generate visible abnormalities in the epithelium. The geometrical modeling of these crypts and the mathemati

8. Comparing CPAP masks during initial titration for Obstructive Sleep Apnea Syndrome: one-year experience
Abstract Objective: Continuous Positive Airway Pressure (CPAP) is the gold standard treatment for OSA. A wide variety of masks are used during CPAP therapy. The aim of the study is to compare polysomnography outcomes during titration for different types of masks (oronasal, nasal and pillow) and assess the impact on PAP titration. Methods: We retrospectivel

9. Better Adequacy of Food Intake According to Dietary Recommendations of National Cholesterol Education Program in Vegetarian Compared to Omnivorous Men
Abstract Background The lower frequency of cardiovascular (CV) risk factors observed in vegetarians compared to omnivores may be due to more appropriate nutrient intake according to recommendations for the prevention of cardiovascular diseases. Objective To compare the dietary adequacy according to the recommendations of the National Cholesterol Educatio

10. Meta-Analysis of Pulmonary Artery Denervation for Treatment of Pulmonary Hypertension
ABSTRACT Introduction: Pulmonary artery denervation (PADN) can reduce the sympathetic nervous system (SNS) activity, reduce pulmonary artery pressure (PAP), and improve the quality of life in patients with pulmonary hypertension (PH). We conducted a systematic meta-analysis of the effectiveness of PADN in the treatment of PH patients. Methods: This is a co

11. Effects of hypercapnia versus normocapnia during general anesthesia on outcomes: a systematic review and meta-analysis
Abstract Background The effect of mild changes in CO2 levels to organ perfusion and tissue inflammation are well known, whereas an influence of hypercapnia under general anesthesia on adverse events as nausea and vomiting, or length of hospital stay is barely examined. The goal of our meta-analysis was to identify possibly positive effects of hypercapnia ve

12. Comparison between dexmedetomidine and fentanyl bolus in attenuating the stress response to laryngoscopy and tracheal intubation: a randomized double-blind trial
Abstract Background and objectives: Laryngoscopy and tracheal intubation lead to a sympathoadrenal response. We compared the efficacy of dexmedetomidine with fentanyl bolus to attenuate this response. Methods: One hundred patients admitted for routine surgical procedures under general anesthesia were enrolled in this double blind, randomized, controlled st
